2024 General Election Precinct Map
The November 2024 election is on the books, but the precinct-level story underneath the topline numbers is where the real lessons live. So we built an interactive map that puts it all in one place. Every contest, every precinct, color-coded and clickable.
What you can explore:
Every race on the ballot — 31 contests, from President, U.S. Senate, and Congress to State Senate and Assembly, county supervisor races, school and college boards, all ten statewide propositions, and local Measures M, N, R, and K.
Margin maps — see which candidate or measure won each precinct, and by how much, on a diverging color scale.
Turnout and roll-off — find where turnout ran hot or cold, and how many voters skipped the down-ballot races entirely.
Registration vs. results — compare a precinct’s party registration against how it actually voted. The mismatches are where persuasion and turnout work pay off.
Mobilization view — estimate where Democratic votes are being left on the table, precinct by precinct, to focus GOTV.
Compare baselines — measure any race against California statewide, the countywide result, Stockton overall, or party registration.
Council-district roll-ups — aggregate precincts into Stockton City Council districts with one click.
Dig into the numbers — hover over any precinct for a detailed breakdown, or export the full dataset to CSV.
Sources include the San Joaquin County Registrar of Voters and the UC Berkeley Statewide Database, with a built-in methodology panel that explains every figure and convention. Built by David Sengthay of Stockton Democrats Together.

About this map · sources & methodology
Data sources. Results: certified San Joaquin County Statement of Vote (Nov 5, 2024 general). Precinct geography & party registration: California Statewide Database (srprec_077_g24, g24 snapshot). Council-district boundaries: City of Stockton open data. Statewide registration baseline: California Secretary of State 15-day Report of Registration (Oct 21, 2024). By city: incorporated city-limit boundaries from county/city GIS (reprojected to WGS84); precincts are assigned to cities using the Statewide Database registrant-based srprec-to-place crosswalk (more complete than centroid assignment for consolidated/mail precincts). Everything outside the eight incorporated city limits is counted as unincorporated San Joaquin County. By Assembly / Supervisor district: official district boundaries (Assembly 2021 final maps; County supervisorial districts) reprojected to WGS84; precincts are assigned by centroid, then pinned exactly to the AD-13, Supervisor District 1, and District 3 precincts that cast ballots in those contests. A city or district shown with a dashed outline and no fill lies outside the selected contest; "X of Y precincts" marks a region only partly inside it.
Reading the map. Margins and vote shares are two-party (two-option for measures) and exclude minor candidates and write-ins. Turnout is ballots cast divided by registered voters. (D) marks the SJDCC-endorsed choice.
Compare baselines. California — the statewide figure for the same contest (its own statewide vote share for President, U.S. Senate, and the propositions; Democratic registration for the registration layer). For the legislative and congressional district races, which have no statewide equivalent, it is the statewide top-of-ticket Democratic two-party share (Harris, 60.4%) as a PVI reference. San Joaquin County / this contest overall — the countywide total. Stockton overall — the citywide Stockton total for the same measure (a candidate’s vote share for a race; Democratic registration for the registration layer). Democratic / Republican registration — the precinct's share of two-party registration.
Analysis views. Roll-off — ballots cast minus votes in the contest: the share of voters who skipped that race. Mobilization opportunity — registered Democrats who did not vote, estimated as Democratic registration × (1 − turnout); it flags where Democratic votes were left on the table. This is an estimate that assumes Democrats turn out at the precinct's overall rate.
Targeting tools. The Targeting tools button opens three planning views for the selected contest: a performance × turnout scatter (every precinct plotted by two-party margin and turnout, with the Democratic-lean / lower-turnout quadrant flagged as the mobilization zone); a GOTV targets ranking of the precincts with the most estimated non-voting Democrats; and a Behind Harris ranking of the precincts where the contest’s candidate ran furthest below the presidential top of the ticket. Precinct profiles: search a precinct number, or click any precinct in those lists, to open a full profile — party registration, turnout, estimated non-voting Democrats, and the result in every contest on the ballot.
